APPARATUS FOR-TESTING OILS. 7

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed November 9.1906. Serial No. 342.717.

To all whom it may concern:

Be it known that I, WILLIAM CHAMPLIN -ROBINSON, a citizen of the United States of America, and resident of the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Apparatus for Testing Oils, of which the following these several tests be conducted simultane-.

ously, and it is also desirable that several oils may be compared in respect to their different characteristics under identical conditions.

With these objects inview I have designed an apparatus in which several oils may be tested simultaneously. The oils are caused to circulate in a closed circuit, part of which circuit they travel by virtue of gravity and part underthe action of suitable v ump-' ing apparatus. During that part 0 their path 0 travel in which they are flowing under the action of gravity their viscosity is tested, and in a portion of the path of travel the oils are made to pass through or over a transparent or translucent guideway lighted from behind, or an opa ue guideway may be used, so that the meo anical consistency,

purity and homogeneity of the oils may be observed, as well as their color. Each oil has a circuit of its own and the several circuits are parallelly disposed, having similar testing apparatus'side by side in each circuit. The several oils are lifted by pumping means and a suitably disposed heater adjacent the oil conductors determines with certainty the temperature of all the oils.

Having set forth the general objects and nature of my invention Iwill now describe an embodiment of the same in detail in connection with the accompanying drawings in which Figure 1 is a view in side elevation'pf my assembled apparatus. .Fig. 2 is a front ele vation of the apparatus shown in Fig. 1.

Referring to the drawings, in the frame 1 of the machine are shown several parallelly disposed oil circuits. These consist of vertical pipes (2) in the rear of the apparatus, terminating at their tops in curved ends (3) disposed vertically over the openings (4:) in the receptacles (5). Outlets (6) from the receptacles are controlled by spig'ots (7), which are disposed vertically over oil runs (8). The lower end of the runs terminate over the open receptacles (9), the outlets from which are in turn controlled by spigots (10) leading to pipes (11), which descend vertically to the base of the apparatus and-then horizontally to pum s (12) by means of which the oil is again li ted through the pipes (2) to the receptacles (5), completing the circuit.

The runs (8) are across a plate of translucent or transparent material and by reason of this and of a light (13) within the apparatus, the homogeneity and purity of the oils may be noted in their passage down the runs (8). i

The viscosity of the oils is determined by their rate and character of flow down the runs (8), and the speed of such fiow may be -vided with adjustable means comprising a tongue (15) attached to the plate and provided with a series of holes (16), any one of which, acoordingto the position of the plate, may be engaged by a pin (17) carried by the frame (1). Y

In order that the viscosity and consistency of the oils may be tested under different and varying degrees of tern erature, a heater (18), preferably of a readi y and accurately ad 'justable character such as an eleotrlc heater, is arranged at the base of the ap aratus adj acent the horizontal portion .0 the pipes (1 1).

In the apparatus shown the pumps are operated from a driven shaft (19) by means of a belt (20.) to a countershaft (21), and from the shaft (21) to the pump-shaft by means of belts (22).

vious. simultaneously across the I pivoted plate.

The advantages of myinvention are ob-' All the/oils pass near each other and In their passage over the plate their relative viscosity and other characteristics are all observable, and the relative actions of the ent grooved plate, and a lig t behind the plate.

2. In an oil testing machine, an oil circuit having as a part thereof, an angularly adjustable transparent runway, and a light be-.

hind the runway.

3. In an oil testing machine, an oil circuit having as a part thereof a sloping transparent runway, and means for regulating the temperature of the oil passing over the run way.

4'. In an oil testing machine, an oil circuit having as a part thereof an angularly ad justable runway, and means for regulating the temperature of the oil in the runway.

5. In an oil testing machine, an oil circuit having as a part thereof an angularly adjustable transparent runway, a light behind the runway, and means for regulating the temperature of the oil in the runway.

6. In an oil testing machine, an oil circuit having as a part thereof a runway for testing the viscosity of .the oil, and for determining the purity of the oil in the circuit.

7. In an oil testing machine, an oil circuit having as a part thereof a runway for testing the viscosity of the oil, and for determining the purity of the oil in the circuit, and means for regulating the temperature of the oil in the circuit.

8. In an oil testing machine, a sloping runway, a pump for lifting the oil to the'top of the runway, a reservoir to catch the oil at the.

foot of the runway, and a passage for the oil from the reservoir to the pump.

9. In an oil testing maclnne, a sloping transparent runway, a light behind the same,

- a pump for lifting the oil to the top of the runway, a reservoir to catch the oil at the 'the oil at the foot of the runway, and a passage for the oil from the reservoir to the pump. I

11. Inan oil testing machine, a sloping runway, a valve controlled oil reservoir at the top of the same, a pump for lifting oil into said reservoir, a second reservoir at the foot of the runway for catching the oil at the foot of the runway, and a passage for the oil from the reservoir to the pump.

12. In an oil testing machine a plurality of adj acently disposed oil runs, whereby the purity of the oils in the several runs and their viscosity may be comparatively determined and means for varying the velocity of flow in the several runs.

13; In an oil testing machine, a series of parallelly disposed oil runs and means for adjusting the angular position of such runs simultaneously. I j

14. In an oil testing machine, a plate having several oil runs across the face thereof, and means for angularly adjusting the plate.

15. In an oil testing machine, a plate hav ing several transparent oil runs across the face thereof, and a light behind the plate.

16. In an oil testing machine, an angularly adjustable plate havmg several transparent Oil runs across the face thereof, and a light behind the plate.

17. In an oil testing machine, an an ularly adjustable plate having several oi runs across the face thereof, and means for regu- -lating the temperature of the oils crossing the plate.
